ABSTRACT

Introduction:

Patients with ST elevation acute myocardial infarction (STEMI) comprise a heterogeneous population with respect to the risk for adverse events. Primary percutaneous coronary intervention (PCI) has shown to be better, mainly in high-risk patients.

Objective:

The purpose of this study was to determine if the Thrombolysis in Myocardial Infarction (TIMI) risk score for STEMI applied to patients undergo primary PCI identifies a group of patients at high risk for adverse events.

Methods:

We identifed patients with STEMI without cardiogenic shock on admission, who were treated with primary PCI. The TIMI and CADILLAC (Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications) risk scores were calculated to determine their predictive value for in hospital mortality. Patients were divided into two groups according to their TIMI risk score, low risk being 0-4 points and high risk ≥5 points, and the frequency of adverse events was analyzed.

Results:

We analyzed 572 patients with STEMI. The c-statistics predictive value of the TIMI risk score for mortality was 0.80 (p=0.0001) and the CADILLAC risk score was 0.83, (p=0.0001). Thirty-two percent of patients classifed as high risk (TIMI ≥5) had a higher incidence of adverse events than the low-risk group mortality 14.8% vs. 2.1%, (p=0.0001); heart failure 15.3% vs. 4.1%, (p=0.0001); development of cardiogenic shock 10.9% vs. 1.5%, (p=0.0001); ventricular arrhythmias 14.8% vs. 5.9%, (p=0.001); and no-refow phenomenon 22.4% vs. 13.6%, (p=0.01).

Conclusions:

The TIMI risk score for STEMI prior to primary PCI can predict in hospital mortality and identifes a group of high-risk patients who might develop adverse events.
RESUMEN

Introducción:

Los pacientes con infarto agudo del miocardio con elevación del segmento ST (IAM CEST), son una población heterogénea por lo que toca al riesgo de eventos adversos. La intervención coronaria percutánea (ICP) primaria mostró ser mejor, principalmente en los pacientes de riesgo alto.

Objetivo:

La propuesta de este estudio fue determinar si la escala de riesgo de trombólisis en infarto del miocardio (TIMI) para IAM CEST, aplicado a los pacientes sometidos a ICP primaria, identifica a grupos de pacientes de riesgo alto de eventos adversos.

Métodos:

Se identificaron a pacientes con IAM CEST sin choque cardiogénico al ingreso, quienes fueron tratados con ICP primaria. Se calcularon las escalas de riesgo TIMI y CADILLAC (Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications), para determinar su valor predictivo de mortalidad intrahospitalaria. Los pacientes se dividieron en dos grupos de acuerdo a su escala de riesgo TIMI, riesgo bajo con 0-4 puntos y riesgo alto con ≥5 puntos, se analizó la frecuencia de eventos adversos.

Resultados:

Se analizaron 572 pacientes con IAM CEST. El valor predictivo del estadístico C de la escala de riesgo TIMI para mortalidad fue de 0.80 (p=0.0001), y la escala de riesgo CADILLAC fue de 0.83, (p=0.0001). El 32% de los pacientes clasificados como riesgo alto (TIMI ≥5), tuvo una alta incidencia de eventos adversos comparada con el grupo de riesgo bajo la mortalidad 14.8% vs. 2.1%, (p=0.0001); falla cardiaca 15.3% vs. 4.1%, (p=0.0001); desarrollo de choque cardiogénico 10.9% vs. 1.5%, (p=0.0001); arritmias ventriculares 14.8% vs. 5.9%, (p=0.001), y fenómeno de no reflujo 22.4% vs. 13.6%, (p=0.01).

Conclusiones:

La escala de riesgo TIMI para IAM CEST, previo a ICP primaria puede predecir mortalidad intrahospitalaria e identificar a un grupo de pacientes de riesgo alto, los cuales pueden desarrollar eventos adversos.
